In volume 12. People asked if Jasdero was a girl, and if Debitto wore underpants, and it was one of those replace-the-comic-text ones.

Also, I like Hoshino's art... I hope it doesn't mean she'll become a shoujo mangaka, though (unless she keeps writing amazing stories). My secret wish is for her to stick to writing the story for a manga and let Obata Takeshi be the artist. :3 I'd love that so much...

Oh yeah. The Japanese version of that is bloody hard to read, but it looks like you're right... SHOCK!

Translations are out in a number of places. Anyway, I can't say it wasn't expected - Debitto was shown in men's clothing (the suit) in the last colour page with the popularity contest. (Road was also in a pink maid dress and tackle-hugging Lenalee.)
